I built a 408 Windsor motor with a 710 lift roller camshaft.
After about 4k miles of street/strip action 4 lifters were junk.
They had not failed to the point of coming apart, but they were not far from it.
I like the sound of FE motors at idle and I know that at low rpm
oil is just not able to lube the roller wheels.
Hopefully these new Schubeck lifters will allow us to prevent future failures.
Thanks for you help guys.
